Important Changes

Discontinued Options on Combination Starters Sizes 0 - 4

  •  "Standard Duty" Type 1 push-buttons, selector switches, and pilot lights allowing for simplified standardization to one operator style for the entire family of combination starters regardless of enclosure type
  • 30A 250V Class H Fuse Clips for NEMA Size 1 are no longer available because fuse clip ratings are sized based on NEC 430-250 typical motor full-load currents
  • Specific Thermal-Mag & Mag-Break Circuit Breaker Ratings are no longer available because breaker ratings are sized based on NEC 430-250 typical motor full-load currents. For example, NEMA Size 1, 460V, 50A Thermal-Mag Breaker amp rating is no longer available

Enclosure Dimensions for Combination Starters Sizes 0 - 4

  • NEMA Size 0 - 2, Type 1 Enclosure no dimensional change (except for fusible disconnect with 100A, 600V fuse clips)
  • For ALL other NEMA Sizes & Enclosure Types the enclosure dimensions have changed. Click here to see list of drawings.
